I feel your pain! Lol. That always drove me nuts as well. Now I use a stiff but shapable wire (clothes hanger) to form a solid connection to the I-bolt used for hanging. Works great for take down risers. I'd think you could do something similar with a one piece, but maybe add a second fishing line around a string groove and alternate ends between coats. Also, the shorter the fishing line used, the less swing you'll get. Use another solid wire with only an inch or two of fishing line around the string groove. Be sure to use a loose, but snug slip knot in the fishing line.
